ENGINE COMPARTMENT FIRE

BY LETTER DATED MARCH 12, 2008, GENERAL MOTORS CORP. (GM) HAS NOTIFIED THE AGENCY THAT IT WILL CONDUCT A SAFETY RECALL (IDENTIFIED BY NHTSA RECALL NUMBER 08V-118) TO ADDRESS A DEFECT IN APPROXIMATELY 207,542 MODEL YEAR (MY) 1997-2003 BUICK REGAL GS AND PONTIAC GRAND PRIX GTP VEHICLES EQUIPPED WITH THE L67 SUPERCHARGED VERSION OF GM'S 3800 SERIES II V6 ENGINE. THE RECALLED REGAL GS VEHICLES WERE BUILT FROM AUGUST 1996 TO JUNE 2003 AND THE GRAND PRIX GTP FROM MARCH 1996 THROUGH JANUARY 2003. ACCORDING TO GM, OIL MAY ESCAPE PAST THE VALVE COVER GASKET ON THE FRONT CYLINDER BANK (CYLINDERS 1-3-5) AND DEPOSIT ONTO HOT EXHAUST SYSTEM COMPONENTS. UNDER CERTAIN CONDITIONS, IT IS POSSIBLE FOR THIS OIL TO IGNITE A SMALL PILOT FLAME, WHICH MAY SPREAD TO THE ADJACENT PLASTIC SPARK PLUG WIRE CHANNEL, THE SPARK PLUG WIRES THEMSELVES, THE PLASTIC ENGINE COVER, AND OTHER UNDER HOOD COMPONENTS. REPORTS INDICATE THIS MOST OFTEN OCCURS ON HIGHER-MILEAGE VEHICLES SHORTLY AFTER THE VEHICLE HAS BEEN DRIVEN AND THEN PARKED. TYPICALLY, THE FIRE WAS DISCOVERED WITHIN 5 TO 15 MINUTES AFTER THE VEHICLE WAS PARKED. DURING THIS TIME WINDOW, UNDER HOOD TEMPERATURES MAY BECOME ELEVATED. SUCH ELEVATED TEMPERATURES COMBINED WITH A LACK OF AIRFLOW THROUGH THE ENGINE COMPARTMENT MAY PERMIT A SMALL PILOT FLAME TO PROPAGATE AND IGNITE OTHER FUEL SOURCES. TO CORRECT THE SAFETY DEFECT, GM WILL INSTALL AN IMPROVED DESIGN FRONT VALVE COVER GASKET AND SPARK PLUG WIRE RETAINER. THIS REMEDY WILL BE SUPPLIED FREE OF CHARGE FOR ALL RECALLED VEHICLES. UNTIL SUFFICIENT PARTS BECOME AVAILABLE TO REPAIR ALL OF THE AFFECTED VEHICLES, GM STRONGLY RECOMMENDS THAT OWNERS OBSERVE THE FOLLOWING IMPORTANT PRECAUTIONS: (1) THEY STRONGLY RECOMMEND THAT OWNERS DO NOT PARK THEIR VEHICLE IN A GARAGE, CARPORT, OR OTHER STRUCTURE; (2) IF OWNERS NOTICE A BURNING ODOR, THEY SHOULD HAVE THEIR DEALER INSPECT THE VEHICLE - THE DEALER WILL INSPECT THE VEHICLE WITHOUT CHARGE; AND (3) USE PREMIUM FUEL (91 OCTANE OR HIGHER) IN THE VEHICL
